I don't know if this is the right place or not , but my computer randomly, or at least seemingly randomly( I have yet to find a pattern if there is one), freezes. when it freezes, both the keyboard and mouse freeze along with the video and sound.
I have an evga p55 mobo an i5@stock 2.66GHZ 4GB corsair RAM 750 watt corsair psu bfg gtx 285 and I am running xp sp3

Is this computer a new build? Was it ever working? Have you installed all the latest drivers for all devices? Do you have the latest firmware for the mobo?
